| 摘要 |
The present invention is directed to novel assays for zero-valent transition metals, and the use of such assays in well logging protocols. The novel assays of the present invention are generally methods or processes for quantitatively and/or qualitatively evaluating the presence of zero-valent transition metals on and/or within samples. Such assays generally involve a digestion process whereby the sample is exposed to carbon monoxide. Transition metals, if present in or on the sample and if contacted by the carbon monoxide, are extracted by the carbon monoxide as metal carbonyl species, the presence of which confirms the presence of transition metals. Such novel assays have enormous predictive power in oil and gas exploration.
